B. Issues on Which DOE Seeks 

Information 

For this RFI, DOE requests comments, 

information, and recommendations on 

the following topics for the purpose of 

determining if DOE should revise its 

NOPR analysis: 

1. DOE seeks comment on the product 

designs and technologies used by 

manufacturers to meet the CEC 

standards, as well as other changes 

made to the products since DOE’s initial 

NOPR analysis. 

2. DOE seeks comment on the product 

costs incurred by manufactures to meet 

the CEC standards, including those 

related to engineering, design, 

manufacturing and product labeling. 

3. DOE seeks information on the 

impact of the CEC standards on 

manufacturer’s supply chain. 

Specifically, DOE seeks information on 

whether manufacturers will continue to 

manufacture products that do not meet 

the CEC standards for sale outside 

California, while selling a separate 

product of similar utility and function 

compliant with CEC standards for sale 

in California 

4. DOE requests information on 

whether there are any types of products 

that have been discontinued from sale 

in California due to the CEC standards. 

DOE is specifically interested in 

whether these discontinued products 

offer consumer utility not offered by 

products compliant with the CEC 

standards. 

5. Finally, DOE seeks information 

from manufacturers on the potential 

costs and burdens of complying with a 

battery charger labeling requirement. 

DOE is also interested in comments 

on other relevant issues that 

participants believe would affect the 

proposed standards for battery chargers. 

DOE invites all interested parties to 

submit in writing by May 28, 2013, 

comments and information on matters 

addressed in this notice and on other 

matters relevant to DOE’s consideration 

of the battery charger and external 

power supply rulemaking. 

After the close of the comment period, 

DOE will review the public comments 

and determine if any changes to the 

proposed standards for the battery 

charger and external power supply 

rulemaking are necessary and 

warranted. 

DOE considers public participation to 

be a very important part of the process 

for developing rulemakings. DOE 

actively encourages the participation 

and interaction of the public during the 

comment period in each stage of the 

rulemaking process. Interactions with 

and between members of the public 

provide a balanced discussion of the 

issues and assist DOE in the rulemaking 

process. Anyone who wishes to be 

added to the DOE mailing list to receive 

future notices and information about 

this rulemaking should contact Ms. 

Brenda Edwards at (202) 586–2945, or

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Hartzell 

Propeller, Inc. propeller models HC-(1, 

D)2(X, V, MV)20–7, HC-(1, D)2(X, V, 

MV)20–8 and HC-(1, D)3(X, V, MV)20– 

8. This proposed AD was prompted by 

failures of the propeller hydraulic 

bladder diaphragm and resulting engine 

oil leak. This proposed AD would 

require replacement of the propeller 

hydraulic bladder diaphragm. We are 

proposing this AD to prevent propeller 

hydraulic bladder diaphragm rupture, 

loss of engine oil, damage to the engine, 

and loss of the airplane.

2013–0130; Directorate Identifier 2013– 

NE–07–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the

Discussion 

We received a report of Hartzell 

propeller failures of the variable pitch 


tkelley on DSK3SPTVN1PROD with PROPOSALS
18256 Federal Register / Vol. 78, No. 58 / Tuesday, March 26, 2013 / Proposed Rules 

propeller hydraulic bladder diaphragm, 

part number (P/N) B–119–2, without 

tab, resulting in engine oil leakage. The 

variable pitch propeller control 

mechanism uses engine oil as a 

hydraulic fluid. Failure of this bladder 

diaphragm results in engine oil loss 

with oil covering the airplane 

windshield and may lead to 

uncommanded loss of engine power. 

This condition, if not corrected, could 

result in loss of engine oil, damage to 

the engine, and loss of the airplane. 

Relevant Service Information 

We reviewed Hartzell Alert Service 

Bulletin (ASB) HC–ASB–61–338, 

Revision 1, dated December 18, 2012. 

The ASB lists the propeller hub models 

that are affected and describes 

procedures for replacement of propeller 

hydraulic bladder diaphragm with a 

new propeller hydraulic bladder 

diaphragm, P/N B–119–2, with tab. 

Hartzell Propeller has redesigned 

bladder diaphragm, P/N B–119–2, to 

include a tab containing the bladder 

diaphragm batch/lot number. The tab 

with batch/lot number is visible after 

installation. The old design bladder 

diaphragm, P/N B–119–2 has no such 

tab. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

removing the old propeller hydraulic 

bladder diaphragm and replacing it with 

the redesigned part. 

Differences Between the Proposed AD 

and the Service Information 

Hartzell ASB HC–ASB–61–338, 

Revision 1, dated December 18, 2012, 

recommends replacement of all affected 

bladder diaphragms within 10 flight 

hours. This proposed AD would require 

replacement of affected bladder 

diaphragms within 12 months of the 

effective date of the AD. FAA risk 

analysis determined the 12 month 

period for compliance is acceptable. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 400 propellers 

installed on airplanes of U.S. registry. 

We also estimate that it would take 

about 4 hours per propeller to replace 

the bladder diaphragm. The average 

labor rate is $85 per hour. We estimate 

parts costs at $53 per engine. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$157,200. Our cost estimate is exclusive 

of possible warranty coverage. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

V, MV)20–8 with a propeller hydraulic 

bladder diaphragm, part number (P/N) B– 

119–2, without tab, installed. 

(d) Unsafe Condition 

This AD was prompted by failures of the 

propeller hydraulic bladder diaphragm and 

resulting engine oil leak. We are issuing this 

AD to prevent propeller hydraulic bladder 

diaphragm rupture, loss of engine oil, 

damage to the engine, and loss of the 

airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain Bombardier, Inc. 

Model DHC–8–100, -200, and -300 

series airplanes. The existing AD 

currently requires replacing certain 

parking brake accumulators. Since we 

issued that AD, we have determined 

that it is necessary to protect the 

hydraulic system and airplane structure 

from possible damage by any faulty 

screw cap or end cap of any 

accumulator. This proposed AD would 

require installing restraint devices 

around the parking brake accumulator 

end caps. We are proposing this AD to 

prevent failure of the parking brake 

accumulator screw cap or end cap 

resulting in loss of the number 2 

hydraulic system and damage to 

airplane structures, which could 

adversely affect the controllability of the 

airplane.

Discussion 

On June 28, 2012, we issued AD 

2012–14–04, Amendment 39–17118 (77 

FR 42956, July 23, 2012). That AD 

required actions intended to address an 

unsafe condition on certain Model 

DHC–8–100, –200, and –300 series 

airplanes. 

Since we issued AD 2012–14–04, 

Amendment 39–17118 (77 FR 42956, 

July 23, 2012), we have determined that 

it is necessary to protect the hydraulic 

system and airplane structure from 

possible damage by any faulty screw cap 

or end cap of any accumulator. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2011–29R1, 

dated May 24, 2012 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Seven cases of on-ground hydraulic 

accumulator screw cap or end cap failure 

have been experienced on CL–600–2B19 

(CRJ) aeroplanes, resulting in loss of the 

associated hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. To date, the lowest number of 

flight cycles accumulated at the time of 

failure has been 6991. 

Although there have been no failures to 

date on any DHC–8 aeroplanes, similar 

accumulators to those installed on the CL– 

600–2B19, Part Numbers (P/N)0860162001 

and 0860162002 (Parking Brake 

Accumulator), are installed on the aeroplanes 

listed in the Applicability section of this 

[TCCA] directive. 

A detailed analysis of the systems and 

structure in the potential line of trajectory of 

a failed screw cap/end cap for the 

accumulator has been conducted. It has 

identified that the worst-case scenarios 

would be the loss of number 2 hydraulic 

system, and damage to aeroplane structures. 

This [original TCCA] directive [which 

corresponds to FAA AD 2012–14–04, 

Amendment 39–17118 (77 FR 42956, July 23, 

2012)] gives instructions to determine the 

part number and serial number of the 

existing parking brake accumulator, and 

where applicable, replace the accumulator. 

Revision 1 of this [TCCA] AD mandates the 

installation of restraint devices around [all] 

the parking brake accumulator end caps to 

hold them in place in the event of an end cap 

failure. 

Uncontained failure of the parking brake 

accumulator screw caps and/or end caps 

could result in loss of the number 2 

hydraulic system, and damage to 

airplane structures, and could adversely
